The thread gets edited and updated from time to time but here’s some of the stuff.

Thought I’d help fellow Cutters out with some links to commonly-replaced parts that can be bought from the OEM (Original Equipment Manufacturer), rather than from BMW (OE). They’re the exact same parts, just without the BMW box / logo, at much lower prices.
I thought most people knew about this but you often see posts about buying the below parts from BMW. Note that there are some parts which the OEM does not make available other than through BMW, e.g. the M3 radiator and water pump, and of course this doesn't work for interior trim, body panels etc. For those you need to go to a dealer, and you can get 10% discount from Cotswold BMW by being a member of this forum.
I can’t promise that these are the absolute cheapest prices out there, so do your own research as well and triple check the part numbers on RealOEM.com
Note that BuyCarParts.co.uk, OnlineCarParts.co.uk, Autodoc.co.uk all seem to be the same platform and have frequent sales.
Hope it helps in some way!
